To paint or not to paint inside of nest box?

Finally going to paint today! I can't believe the coop I have been working on has taken 2 1/2 months...but finally get to put on primer today! (It's only 4'x4'...I must be the slowest builder on earth...)

I'm planning on painting the inside of the coop semi-gloss white. Right now the nest boxes are unpainted plywood inside. Can I go ahead and prime and paint the inside of the nest boxes semi-gloss white? I have read that hens like dark (secluded) areas to lay. For me it would be easier to clean to have it semi-gloss but to save from having to buy another can of dark paint just for the nest box, will white do?

Is there any possibility that my hens will refuse to use the nest box if the paint color is too light??

I don't paint the interior or the nest boxes because I think the hens feel more secure when it is a little darker. I place the nest boxes in the darkest corner of the coop. But to each their own. I'm sure others have had great success painting everything.

Just a paint reminder: Construction grade is good paint and it costs less. The down side is that are you limited as to choice of colors, but I'd like white for my nest boxes.
I have to politely disagree with darkmatter on painting the nest boxes. Every place my birds go needs to be cleaned, and it will be easier to clean a painted piece of wood than to clean an unpainted or untreated piece. Just MHO.

I used spar varnish for the inside of mine. I figured the chickens wouldn't be as tempted to peck it, although I am a chicken noobie and based that on nothing really. I also was thinking of cleanlieness when I decided to paint mine.
